Abstract

The input device and detection device each comprise separate electrodes (20) comprised of an electrode for detecting input in a vertical direction and a plurality of electrodes for detecting input in a horizontal direction and arranged separately on the surface, an elastic body (6) which faces the above separate electrodes with a predetermined space therebetween, at least a portion opposite to the separate electrodes having conductivity, a thin portion (16) being provided opposite to the electrode for detecting input in a vertical direction, a storage depressed portion (15) being formed on the thin portion, and the space between the elastic body and the separate electrodes changing by input, a slider (2) connected tot he elastic body and movable only in a horizontal direction, a hard pressing body (5) stored in the storage depressed portion of the elastic body, and a key top (1) whose portion opposite to the pressing body is movable in a vertical direction, wherein when the slider is moved in a horizontal direction, the elastic body deforms and the space between the conductive portion of the elastic body and the electrodes for detecting input in a horizontal direction changes, and when the key top is pressed, the thin portion of the elastic body deforms through the pressing body and the space between the thin portion and the electrode for detecting input in a vertical direction changes.
